Effects of Noise Pollution

It still blows my mind how often I see parents taking their children to events that are clearly damaging to the child's hearing.  I've noticed hearing loss in my left ear and I'll bet it's because, when I'm driving if I have the windown down at all, I am exposed to motorcycles and the many many vehicles with souped up engines.  When there are one of these vehicles in the left lane I have to slow down so that the vehicle gets way ahead of me because it is so painful to my ears.  As I've mentioned before I likely have something to the effect of presbycusis.
